Caprylic/capric triglyceride (INCI: Caprylic/Capric Triglyceride), also called MCT, is a lightweight, fractionated (shorter-chain) emollient oil produced by combining coconut-derived medium-chain fatty acids with glycerin. It is not a pure botanical oil but a standardised lipid made by selecting and restructuring specific fatty acids, making it a defined mixture rather than a single molecule. It provides slip and spreadability without a heavy feel and is used as a softener and carrier in a very wide range of formulas. Its greater oxidation resistance than pure botanical oils and absence of odour make it suitable for stable, lightweight formulas. It appears on labels as 'Caprylic/Capric Triglyceride'. For Klaris, it is best assessed not as a single 'active', but as a foundational lipid shaping texture, spreadability and carrying capacity, alongside the other lipids and the intended texture.
i. Cosmetic Functions
Frequently Discussed Effects
The following headings summarise areas of effect frequently discussed in the literature; visible results in each area require regular use and a suitable formula.
Lightweight Softening
Spreads lightly and silkily over the skin, feeling less dense than heavy botanical oils.
Active Carrier
Acts as a solvent or carrier for oil-soluble ingredients such as retinol and vitamin E.
Texture Adjustment
A supporting lipid that adjusts the spreadability and slip of creams and serums.
Mechanism
What Happens Within the Skin?
The following points summarise mechanisms from dermocosmetic literature in plain English. Klaris presents them as background information to help readers understand the context, not as medical claims.
Step 1
Lightweight Emollient Spread
Spreads lightly and silkily over the skin, feeling less dense than heavy botanical oils.
Step 2
Active Carrier and Solvent
Acts as a solvent or carrier for oil-soluble ingredients such as retinol and tocopherol.
Step 3
Texture and Slip Adjustment
A supporting lipid that adjusts the spreadability and slip of creams and serums.
Step 4
Relative Oxidation Resistance
Its fractionated structure makes it more resistant to oxidation than pure botanical oils and odourless; it is chosen for stable formulas.
Step 5
A Defined Mixture
Not a single molecule, but a standardised lipid made by restructuring selected coconut-derived medium-chain fatty acids with glycerin.
ii. Role in the Formula
How Is It Read on a Label?
Caprylic/capric triglyceride is one of the most common lightweight emollients in cosmetics. More resistant to oxidation than pure botanical oils and odourless, it is chosen for stable, lightweight formulas. It generally appears at 1% - 15% as a carrier or texture adjuster. Although 'oil' may suggest greasiness, this ingredient stays light in most formulas.
A Closer Look · pH, Stability, Synergy
Caprylic/capric triglyceride is one of the most common lightweight cosmetic emollients and serves two main formulation purposes: providing light softness and spreadability at the skin's surface, and carrying oil-soluble actives such as retinol and tocopherol. Its fractionated, medium-chain structure distinguishes it from pure botanical oils in two ways: it is more oxidation-resistant and odourless, making it useful for shelf life and texture consistency. It is generally used at 1%-15% as a carrier or texture adjuster. Although 'triglyceride' and 'oil' may suggest a heavy, greasy feel, this ingredient remains distinctly light in most formulas. Automatically classifying it as 'heavy' out of concern about congestion is misleading; feel and behaviour depend on the complete formula. Although derived from coconut, it is not the same as pure coconut oil: compared with coconut oil's heavier structure and different acid profile, caprylic/capric triglyceride is a lighter, standardised lipid of selected medium-chain acids. As a defined mixture rather than a single molecule, it is assessed through its cosmetic ingredient family and formula context, not a single chemical record or CID. Klaris considers its role (carrier or main emollient), accompanying lipids and intended texture as a whole.

iii. Sensitivity Advisory
A Note on Extra Care in Context
Generally well tolerated across a broad range of profiles. Rich formulas can be assessed contextually for highly congestion-prone profiles, but its light nature makes it comfortable for most profiles.
A sensitivity advisory is not an instruction for use; where individual health circumstances, pregnancy or known sensitivities are involved, discussing the decision with your doctor may be a more contextual approach.
Common Misconceptions
Frequently Confused Points
Common Belief
Because its name includes 'triglyceride' and it is an oil, it is heavy and clogs pores.
A More Contextual Reading
Its fractionated structure keeps caprylic/capric triglyceride distinctly light in most formulas. Although 'oil' suggests greasiness, feel and behaviour depend on the whole formula; there is no automatic rule that it causes congestion.
Common Belief
It is the same ingredient as coconut oil.
A More Contextual Reading
Although coconut-derived, it is not pure coconut oil. It is a lighter, more stable, odourless fractionated lipid made from selected medium-chain fatty acids.
Common Belief
It is just a filler.
A More Contextual Reading
As a lightweight emollient and active carrier, it is a functional foundational lipid that shapes texture, spreadability and the delivery of oil-soluble actives.
Common Belief
It is always less nourishing than natural oils.
A More Contextual Reading
Its role is different: it is a lightweight emollient and carrier. Nourishment is assessed from the lipid composition of the whole formula, not one ingredient.
